 Docker container for wsdd.py
+
+## Running container
+### From command line
+docker run --net=host -e HOSTNAME=$(hostname) jonasped/wsdd
+
+It is important that the container is run with the argument --net=host and that the environment variabel HOSTNAME is set to the same value as your Samba netbios name. Samba netbios name defaults to the hostname. 
+### From docker compose
+A docker-compose.yml file could look like the one below. 
+        wsdd:
+                image: "jonasped/wsdd"
+                environment:
+                        - HOSTNAME=NETBIOS_NAME
+                restart: unless-stopped
+                network_mode: "host"
